Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a moisture barrier between the heat insulating layers.
The present invention relates to a panel having an airtight layer and a house in which the panel is installed from the outside of a frame.

[0002]

2. Description of the Related Art Heretofore, in this type, the following has been done. Insulation and airtightening of houses are progressing especially in areas with severe winter conditions, where
Emphasis has been placed on measures against condensation (internal condensation) in the heat insulation layer in the cold season. Therefore, it is a general construction method to form the moisture-proof (also airtight) layer on the indoor (high temperature) side.

[0003]

The problems described in the prior art have the following problems. 1. However, as heat insulation and airtightness improve, energy-saving air conditioning in summer is also possible, and in combination with the nationwide movement of heat insulation and airtightness, the demand for air conditioning in areas with high outdoor temperature in summer will increase. It is expected to increase. 2. By the way, in winter and summer, the conditions inside and outside the house are completely reversed, so if the construction method is mainly in winter (when heating), there is a concern that dew condensation will occur near the inside of the heat insulation layer in summer (when cooling). . This summer type dew condensation easily overlaps with the high temperature and high humidity season, and thus easily leads to decay of the wooden frame. Therefore, a safe countermeasure for both winter and summer is to provide a moisture-proof (airtight) layer in the middle of the heat insulating layer. However, it is difficult to form a moisture-proof (airtight) layer in the middle of the heat insulating layer by the construction method in which the inside of the wall is used for heat insulation like a conventional house.

The present application has been made in view of the above problems of the prior art, and an object of the present application is to provide the following. That is, in the present application, the panel with the moisture-proof layer incorporated in the middle of the heat insulating layer is tightly bonded from the outside of the wooden frame so that the heat insulation is airtight, and a safe house is secured against internal condensation of both summer and winter types. It is the one we are trying to provide.

[0005]

In order to achieve the above object, the present invention is as follows. That is,
In the case of the present application, the heat insulating material 3 filled in the panel frame 2 is composed of a high density fibrous heat insulating material portion 3A made of glass wool or the like located on the outside air side of the panel frame and polystyrene or the like located indoors. And a plate-shaped heat insulating material portion 3B, and a moisture-proof and airtight layer 3C made of a poly film or the like is stretched between the both heat insulating material portions 3A and 3B. Further, on the surface of the high-density fibrous heat insulating material portion 3A. Is a panel in which a moisture-proof / airtight layer is formed in the middle of a heat-insulating layer on which a wind-proof layer 3D made of paper or film is stretched. Houses have a panel (wood or iron) with a panel with a moisture-proof and air-tight layer formed in the middle of the above-mentioned heat insulation layer.
It is tightened from the outside.

EXAMPLES Examples will be described with reference to the drawings. 1
Is a panel in which a moisture-proof / airtight layer is formed in the middle of the heat insulating layer as the first invention (hereinafter referred to as a panel), and a panel frame 2;
The heat insulating material 3 is filled in the panel frame, and the left and right vertical furring strips 4, 5 attached to the left and right side surfaces of the panel frame. The panel frame 2 has upper and lower frames 2A and 2B and left and right frames 2C and 2D connected to each other in a square shape in the front view.

The heat insulating material 3 is composed of a high density fibrous heat insulating material portion 3A made of glass wool or the like located on the outside air side of the panel frame and a plate heat insulating material portion 3B made of polystyrene or the like located indoors. , These two heat insulating material parts 3A,
A moistureproof and airtight layer 3C made of a poly film or the like is stretched between 3B, and a windbreak layer 3D made of paper or a film is stretched on the surface of the high-density fibrous heat insulating material portion 3A. Reference numeral 3E is a reinforcing bar that is stretched vertically and horizontally in the filling portion of the high-density fibrous heat insulating material portion 3A in the panel frame 2.

Referring to FIG. 5, reference numeral 1A is a house in which the panel 1 according to the second invention is installed from the outside of the frame assembly. The construction procedure is as follows. The vertical structure is as follows. 1. A vertical furring strip 7 for panel mounting is nailed to the pillar 6. 2. Adhesive soft urethane 8 is attached to the vertical furring strip 7. 3. The panel 1 is tightly connected with the nail 9.

The horizontal direction is constructed as follows. 1. The soft urethane 8 with glue is pasted on the upper frame 2A of the panel 1 which has already been attached. 2. The panel 1 located above is set on the upper surface of the panel 1. 3. The upper frame 2A of the panel 1 located below and the lower frame 2B of the panel 1 located above are tightly connected by oblique nailing. In this way, after the panel 1 is stretched, the panel 1 is stretched.
The exterior material 11 is stretched on the outside air side through the ventilation layer 10, and the interior material 12 is stretched on the indoor side of the pillar 6.

Reference numeral 13 is a foundation, and 13A is a heat insulating material for external heat insulation. In addition, FIG. 6 shows a building 15 with a gently sloping roof, which is 15A.
Is a frame set, 15B is a wall formed by tightly connecting the panel 1, 15
C is a ventilation layer, and 15D is a heat insulating material for external heat insulation to the foundation. FIG. 7 shows a horizontal roof type building 16 in which 16A is a frame, 16B is a wall formed by tightly connecting the panels 1, 16C is a ventilation layer, and 16D is a heat insulating material for external heat insulation to the foundation.

The operation will be described together with the effects.

[0012]

Since the present invention is configured as described above, it has the following effects. 1. Forming a moisture-proof layer in the middle of the heat-insulating layer is extremely difficult in the field construction, but by forming that part into a panel, it can be supplied as an easy and reliable component. that is,
It leads to labor saving and rationalization of on-site construction. 2. By separating the frame (wood or steel frame) and the heat insulation (airtight) layer part, the frame is released from the risk of internal condensation and the durability problem due to decay (wood) or rust (iron) is solved. 3. By reducing the troubles caused by dew condensation in the walls in winter (when heating) and summer (when cooling), and changing the combination of the thickness of the heat insulating material and the moisture-proof (airtight) layer according to the natural conditions of each region, Application from north to south) is possible.
